Ettercap was so powerful that its authors, ALoR and NaGA, eventually got a call from the Milan police department. But the cops didn’t want to bust the programmers for enabling hacker attacks. They wanted to use Ettercap to spy on citizens. Specifically, they wanted ALoR and NaGA to write a Windows driver that would enable them to listen in to a target’s Skype calls.

That’s how a small tech security consultancy ended up transforming into one of the first sellers of commercial hacking software to the police. ALoR’s real name is Alberto Ornaghi and NaGA is Marco Valleri. Their Milan-based company, Hacking Team, now has 40 employees and sells commercial hacking software to law enforcement in “several dozen countries” on “six continents.”
